Hi there -Jace_Rahilly,
Welcome to the Community Forum. We do hope you find it a valuable resource.
Firstly, we do ask that in the future, queries such as these are posted on the MYOB Essentials Community Forum for both your benefit, as well as for other clients that may have experienced the same issue.
Unfortunately, there is no way of retrieving the data entered prior to a quote/invoice being saved as Essentials only saves the information upon actually recording the transaction.
We do understand how frustrating losing all your work must be. As a tip, we have found that some clients do find it helpful to save the quote or invoice periodically to keep a record of their details. As these saved transactions can be edited, you can then go back into the quote and continue working on it, being a bit more reassured that if it does time out or logs you out again for any reason, that at the very least you will not have lost all your work.
Cheers,
Tallie
